Ran is my wife's stepdaughter. I've raised her like my own child, but today she finally brought home her boyfriend. I see, she's reached that age already. I feel a little lonely, but as long as Ran is happy, that's fine with me. As a father, I won't do anything to get in the way of their love. ...Or so I thought, but when I handed Ran a bath towel in the bathroom, a dark emotion suddenly began to grow. I have to protect Ran before some random young bastard takes her virginity...!
